Hikers are typically advised to stay at least 300 yards away from a bear, McLaughlin said.

The bear, which weighed an estimated 600 pounds, was shot and killed by a state trooper as he was defending the spot where White's remains were found.

The incident began Friday afternoon when three hikers found a camera, a backpack and evidence of a violent struggle, including torn clothing and blood, along the Toklat River. They reported what they found to park rangers, who sent a helicopter and a fixed-wing aircraft to search for White, officials said.

Rangers in the helicopter determined that the bear had dragged White's remains from a flat expanse along the river to a more secluded brushy area 150 yards away, where it stored its food.

Investigators determined the bear had killed White after reviewing the bear's stomach contents, the images on the camera and other evidence, officials said. The pictures showed the bear foraging in the brush along the Toklat River, McLaughlin said.

"For a good [part] of that time, the bear was unaware that anyone was there," McLaughlin said. "There were no dramatic signs of aggression.">>>>>>The bear was surprised and the attack followed!!

Bear attacks have resulted in minor injuries in recent years, McLaughlin said. But several decades have passed since anyone in the park was severely mauled, she said.

White had been camping in a backcountry section of the park for three nights when he was killed. Park officials imposed an emergency closure prohibiting all hiking and camping in that portion of the park and others nearby until further notice.

Although no other park visitors were seen near the site of the bear attack, park employees contacted three backpackers in adjacent areas Saturday and flew them by helicopter to the Toklat River Rest Area.

Many questions go unanswered concerning the hikers knowledge of bears and safety precaution that should be taken in bear habitat……!

Ken,
Thanks for the link. I was initially deterred by the length of that video, but it is good information presented in an entertaining style. Dispels many of the conventional wisdom myths about human-bear interactions.
